SANDPAPERING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 499,014, dated June 6, 1893.

Application filed January 6, 1893. Serial No. 457,437. (No model.)

To all whom it may concern.-

Be it known that we, WILLIAM H. DOANE and J oHN SOFGE, citizens of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Sandpapering-Machines; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in. the art to which it appertains to make and use the same.

Our invention is an improvement on the sand papering machine covered by Letters Patent of the United States No. 238,095, granted February 22,1881,to WV. H. Doane and G. \V. Bugbee and consists in the novel features of construction and combination of parts hereinafterfully described, reference being had to the accompanying drawings which show one form in which we have contemplated embodying our invention and the said invention is fully disclosed in the following description and claims.

In the said drawings Figure 1 represents a side elevation of a sand papering machine embodying our invention. Fig. 2 is a top plan view of the same. Fig. 3 is an end view of the machine. Figs. 4 and 5 are detail views of parts of the mechanism. Fig. 6 is a partial side elevation of the machine show ing the two upper sections elevated to give access to the sand papering rollers. Fig. 7 is a partial side elevation of the machine showing a slightly modified form of elevating devices.

One of the objects of our invention is to construct a sand papering or polishing machine in which access may be had readily to the sand papering or polishing rolls for the purpose of examining, renewing the paper, adjusting the rolls or other purpose.

In the drawings we have shown the frame work of the machine composed of three parts designated A, A and A The part A is the base portion of the frame and is provided with suitable bearings to receive a series of sand papering or polishing rollers B B 13. Upon the base part A of the frame rests the middle portion A of the frame in which are mounted the lower feed rolls 0 C. This middle section of the frame is also provided with the bed plate D to support the work. Above the middle section A of the frame is the top section A in which are mounted the upper feed rolls E E. The upper section A is provided at each corner with a vertically disposed hollow column a which extends downwardly and engages a recess orbearing in the middle section A. The columns are preferably circular in cross section and engage the bearings or recesses in the section A in such a manner that said bearings form guides for said column in the upward and downward movements of top section A The columns a are provided with interior screw threads and each column is engaged by .a screw threaded portion fof a screw shaft F supported vertically in hearings in the base portion A of the machine frame.

We provide power mechanism for simultaneously rotating the screws F and raising or lowering the top section A of the frame. To this end each of the screw shafts F is provided adjacent to its lower end with a beveled pinion f and the shafts at one side of the machine are each geared with the corresponding shaft at the other side of the machine by means of a horizontal counter shaft G provided with pinions g for engaging the pinions f and effecting the simultaneous movement of the two screw shafts F. Adjacent to one side of the machine a longitudinal shaft H is mounted in suitable bearings h and is provided adjacent to its extremities with pinions h which engage the pinions f of the vertical screw shaft located at that side of the machine. The shaft II extends beyond the frame of the machine at one end and is provided with a gear wheel h by which motion is imparted to the shaft.

K represents the driving shaft of the machine mounted transversely thereof in suitable bearings 70 and provided at one end with a band wheel It. A longitudinally disposed connecting shaft L is mounted at the end of the machine adjacent to the pinion h of shaft H and extends from the point adjacent to the driving shaft K to a point beyond the end of the frame A where it is provided with a pinion Z meshing with the pinion 71 of shaft H, see Figs. 2 and 3. We also provide means for imparting motion in both directions to the connecting shaft L from the driving shaft K, which consists in this instance of the devices shown in detail in Fig. 4 and indicated in Figs. 2 and 3. Upon the driving shaft K are loosely mounted a pair of oppositely beveled gears k located on opposite sides of the connecting shaft L and engaging a beveled gear Z rigidly secured to said shaft. Each of the gears 70 k is provided with a hollow friction clutch member 70 and between the said gears 70 70 a clutch hub 10 provided at each end with a friction cone is is mounted upon a spline or feather on the driving shaft K. An operating lever K is pivoted to asuitable cross bar of the frame A at k and has an arm k engaging the clutch hub 7.0 It will thus be seen that by means of the operating lever K the clutch hub may be moved to bring one of its cones into engagement with the clutch member of either of the gears k k and thus impart motion in either direction to the connecting shaft L, the horizontal shaft H and the fourscrew shafts F. By means of the devices just described it will be seen that the top section A may be raised or lowered by throwing the operating lever K in one direction or the other and the upper feed rollers will thus be adjusted by power actuated mechanism to the required distance from the lower feed rolls to accommodate the work passing through the machine. We also provide devices for coupling the sections A A together so that they maybe simultaneously raised bythe power actuated mechanism, to such a height above the base section A of the frame as to give access to the sand papering rolls when desired. In Figs. 1, 2 and 3 we have shown the top section A provided with pivoted links M bolted or otherwise secured to the sides of the top section and depending below the same, and the middle section A is shown provided with screw threaded studs or bolts m which may be made to engage apertures m in the links M. The top section A will be lowered upon the middle section A, the parts coupled together by placing the links M in engagement with the lugs or bolts m and securing them by means of nuts m if desired, and the power actuated raising mechanism will then elevate both of the upper sections A A of the frame far enough above the base section A to give access to the sand papering rolls. The parts are shown in this position in Fig. 6. In this figure we have shown the links M provided with open slots in theirlower ends to engage headed lugs m or bolts secured to and projecting from the middle section A.

In Fig. 7 we have shown a slightly modified construction in which the hollow column secured to the top section A in the first described form is dispensed with and the screw shafts are made longer and caused to engage guiding apertures in the middle section A and screw threaded apertures in the top section A The operation however will be the same as before described.

In Fig. 5 we have shown a slightly modified form of gearing for connecting the shaft L with the longitudinal shaft II. In this form the shaft II is provided with a gear h of less diameter than the gear 72, shown in Fig. 3, which engages a pinion n on an intermediate gear stud N. A pinion n is also mounted upon the stud N in such a manner as to rotate with the pinion and the said pinion n meshes with the pinion Z on the connecting shaft L.

The feed rollers will be driven by expansion gearing in any suitable manner and the machine is also provided with the usual chute 0, see Fig. 1, to conduct the dust from the machine.

The rolls B B B will be covered with sand paper ordinarily, but we do not limit our selves to the use of sand paper, as the rolls may be covered with emery, or any other suitable abrasive or polishing material which is best fitted for the work to be done. We therefore term such rolls the polishing rolls.

We do not desire to limit ourselves to the exact details of construction shown and described herein, as variations may be made therein without departing from the spirit of our invention.

What we claim, and desire to secure by Letters Patent, is

1. In a sand papering and polishing machine the combination with the main frame comprising the base section provided with polishing rolls, the middle section carrying the lower feed rolls, and the top section carrying the upper feed rolls, of adjusting devices located in the base section engaging the top section for adjusting said upper feed rolls, and devices for coupling said middle and top sections together whereby said adjusting devices may be made to raise both sections bodily to give access to the polishing rolls, substantially as described.

2. In a sand papering machine the combination with the main frame comprising the base section provided with the polishing rolls,

the middle section carrying the lower feed rolls, and the top section carrying the upper feed rolls and provided with columns engaging guiding apertures in the middle section, of screw shafts supported in said base section and engaging said columns for adjusting said top section independently of said middle section and links for coupling said top and middle sections together whereby they may be simultaneously raised to give access to said polishing cylinders, substantially as described.

In testimony whereof we affix our sign atures in presence of two witnesses.
